 as maybe, composed of vegpe tables. — See Feeding. 



Fits in dogs are a very common consequence of confine- 

 ment ; and it is very usual for a dog, particularly a sporting 

 one, who has been closely and long confined, on gaining his 

 liberty, to experience a violent fit. 1 have observed the same 

 occur in dogs after long voyages. 



Exercise should, therefore, be allowed to every dog ; and, 

 as this should be done in proportion to his other habits, to 

 lay down any general rule on this head is nearly impossible. 

 The exercise of fat ones should not be violent, but it should 

 be long continued : when it is too violent, it is apt to pro- 

 duce fits or cough, and thus, in the end, may prove the pa- 

 rent of asthma. Sporting dogs require gallops, to fit them 

 for their work, and to give them wind ; and, for this pur- 

 pose, they should be taught to follow a horse. Lesser dogs, 

 and all who are at other times confined, require at least two 

 hours' exercise every day.

£!t/eSj Diseases oJ\ 



The eyes of dogs are subject to several kinds of disease. 

 The most common of these is an ulceration of the cornea, or 

 transparent part of the globe of the eye, from a symptomatic 

 ophthalmia occasioned by distemper. This affection of the eyes 

 usually commences by a blueness, or sometimes by a perfect 

 opacity of the transparent portion ; in the centre of which a 

 speck may be frequently seen, which gradually accumulates 

 to a small abscess, and bursts, leaving an ulcer. This ulcer 

 sometimes remains stationary till the distemper amends : in 

 others it extends, and involves the whole pupil in an ul- 

 cerative process. In some cases a fungus forms, and pro- 

 trudes outwards. One circumstance is peculiarly worthy of 

 remark in this affection, which is, that the eye can become
